The object of the invention is to provide an oil spray of this character adapted to 1o apply the proper amount of oil for the treatment adapted to the particular case.

A yfurther object is to provide .a device of this character and which is of simple and durable construction, reliable in operation,

l5 easily controlled and manipulated and coinparatively inexpensive to manufacture.

Other objects and advantages of the invention reside in certain novel features of the construction, combination and arrangeio ment of parts which Will be hereinafter more fully described and particularly pointed out in the appended claim, reference being had to the accompanying drawings forming part of this specification, and in which:

Figure l is a view, partly in section and partly in elevation, showing the oil spray constituting the present invention organized with a douche and speculum; and

Figure 2 is a view in section on line 2 2 3o of Figure l.

Referring to the drawings, the numeral 10 designates the douche and speculum forming the subject-matter of my co-pending application filed March 15, 1923, Serial No.

The oil spray which constitutes the resent invention includes a barrel 5() o cylindrical form which is removably mounted in the bearing bushing of the douche and speculum. The upper end of the barrel 40 is provided with a perforated head or cap 51 having threaded connection with the interior of the body of the barrel and the lower end of the barrel may be closed by a head 52 (although this head 52 may be omitted if de- 45 sired). A plunger 55 is slidably itted in the barrel 50 and is actuated by a. plunger rod 56 which extends exteriorly of the barrel and terminates in a knob 57. The plunger rod 56 operates through a bracket 58 fixed to the 50 barrel at the lower end thereof.

In order to provide for the measuring of a charge of oil the rod 56 may be provided with a number of annular notches 59 cooperable with a spring detent 60 IiXed to the 55 head 52 and biased so as to spring into the notches 59 when the same are brought into alinement with the detent. The detent is provided with a finger piece 61 to provide for the release of the same. 60
